HEAT EXCHANGING APPARATUS Russian patent published in 1995 - IPC

FIELD: heat engineering. SUBSTANCE: heat exchanging apparatus has vertical gas- turbine chamber 1 with cooling walls, piping-rib heat emitter 7 with inner screen 11, and branch pipes for cooled 3 and cooling 4 heat carriers, evacuation, and filling with the gas. The gas-vacuum chamber has ring cross-section. Additional emitter 6 with outer screen 11 is mounted inside emitter 7. The screen and inner screen define the space which is in communication with gas- vacuum chamber 1 from the bottom and top. Branch pipe 4 for introducing the heat carrier cooling walls of gas- vacuum chamber 1 is positioned at its top part. Emitters 11 are made up as heat pipes 10. Fan 12 is mounted inside gas-vacuum chamber 1. The fan provides circulation of the gas. EFFECT: enhanced efficiency. 4 cl, 1 dwg
